測試@ubuntu:~$ java -version
The program 'java' can be found in the following packages:
* default-jre
* gcj-5-jre-headless
* openjdk-8-jre-headless
* gcj-4.8-jre-headless
* gcj-4.9-jre-headless

下載Tar jdk並更新java路徑
sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.7.0_79/bin/java 1
不是它顯示java版本。
test@ubuntu:~/elasticsearch-2.3.4$ java -version
java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)
